Intumescent Pipe Collar

A high performance graphite based intumescent material contained within a metal sleeve, which on exposure to heat from a fire will expand many times its own volume to crush and fill the void left by collapsing upvc pipes or trunking.

Tested to BS 476 Part 20 up to 4 hour fire resistance
Can be surface mounted or cast
Light and compact design, easy to install, maintenance free

The collars are suitable for use in multi-storey office and flat developments, hospitals and hotels or anywhere upvc pipes or trunking pass through fire compartment floors or walls. The collar can be surface mounted or cast into the floor or wall and secured in place with non-combustible screws or steel anchors. The collar must be fitted on either side of the penetration when both sides of the wall are a fire risk.
